Description

Pre-laid anti-sticking waterproof structure for underground engineering Technical Field The utility model relates to the technical field of waterproof structures, in particular to a pre-laid anti-sticking waterproof structure for underground engineering. Background The waterproof construction that the reverse-adhesion waterproof construction of spreading in advance is used for underground structure prevents external groundwater infiltration major structure, and current reverse-adhesion waterproof construction of spreading in advance is as shown for the patent of application number CN201320005710.4, and it includes concrete basic unit, waterproofing membrane, concrete major layer and mounting, and during the construction, waterproofing membrane lays on concrete basic unit, and the mounting runs through waterproofing membrane, fixes waterproofing membrane on concrete basic unit, then pours concrete major layer on waterproofing membrane again. When the pre-paved anti-sticking waterproof structure is constructed, the fixing piece penetrates through the waterproof coiled material to be fixed, the fixing piece leaves perforations on the waterproof coiled material, and external groundwater easily permeates into the concrete main body layer through the perforations. Disclosure of utility model The utility model provides a waterproof structure which is difficult to permeate water in order to solve the defect that the existing pre-paved anti-adhesion waterproof structure is easy to permeate water.
